UC3843 IC - (SMD SOP-14 Package) - Current-Mode PWM Controller 14 Pin IC

The UC3843 series are high performance fixed frequency current mode controllers. They are specifically designed for Off−Line and DC−DC converter applications offering the designer a cost−effective solution with minimal external components. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET. Also included are protective features consisting of input and reference under voltage lockouts each with hysteresis, cycle−by−cycle current limiting, programmable output deadtime, and a latch for single pulse metering.


Features:-

  • Trimmed Oscillator for Precise Frequency Control
  • Oscillator Frequency Guaranteed at 250 kHz
  • Current Mode Operation to 500 kHz
  • Automatic Feed Forward Compensation
  • Latching PWM for Cycle−By−Cycle Current Limiting
  • Internally Trimmed Reference with Under voltage Lockout
  • High Current Totem Pole Output
  • Under voltage Lockout with Hysteresis
  • Low Startup and Operating Current
  • This is a Pb−Free and Halide−Free Device
